EXPECTED RETURN A stock's returns have the following distribution: Demand for the Probability of this Rate of Return If Company's Products Demand Occurring This Demand Occurs Weak 0.1 (50%) Below average 0.2 (6) Average 0.5 18 Above average 0.1 33 Strong 0.1 48 1.0 a. Calculate the stock's expected return. Round your answer to two decimal places. % b. Calculate the stock's standard deviation. Do not round intermediate calculations. Round your answer to two decimal places. % c. Calculate the stock's coefficient of variation. Round your answer to two decimal places. EXPECTED RETURNS Stocks A and B have the following probability distributions of expected future returns: Probability A B 0.1 (5%) (26%) 0.3 6 0 0.3 11 21 0.2 20 30 0.1 38 49 a. Calculate the expected rate of return, rb, for Stock B (ra = 12.40%.) Do not round intermediate calculations. Round your answer to two decimal places. % b. Calculate the standard deviation of expected returns, CA, for Stock A (OB = 20.17%.) Do not round intermediate calculations. Round your answer to two decimal places. % c. Now calculate the coefficient of variation for Stock B. Round your answer to two decimal places
